Until now, the quick creation dialog of the calendar view assumed that
the underlying model used a 'name' field for quick creation, with a
graceful degradation if it was not the case (redirect to the form view).
This prevented quick creation of models created through customizations
(for example).
This commit adds a `create_name_field` attribute on the view declaration
(similarly to many2one field) that allows to specify the field to use
during quick creation.
